if I see KVS availability on LH I know it its POS US. Does that mean LH US hotline will be able to issue the ticket for me even if I am paying with a German CC?

Seeing availability in W on KVS, while lh.de gives me H fares only on FRA-MEX r/t. So quite some money in that case.

Thanks for any info.

Essentially, yes -- you can take advantage of the more favourable US POS Availability by calling LH Reservations in the US, as long as the Fare does not have a Sales Country restriction (the Fare in question does not):

Expedia and other US POS OTAs will not have access to the 'vorzugpreise' ie the preferred fares TA/OTAs in Germany have. This can make a difference of 35-100€ on the base fare. The trick around that is to have your german TA waitlist you in the lowest booking class that is available, then call the US to have your specific segment be updated with the US pos availbility and then ask your german TA to ticket with the preferred fare.

Hehe okay! That sounds very complicatd all of a sudden
But thanks for the useful insight!

Slightly OT: Is it possible to change a return ticket BOS-FRA-TXL to JFK-FRA-TXL. Ticket is in S and issued in Germany. I remember that I once changed YUL-FRA into JFK-FRA without any problems, so I was hoping to do the same again?!
